T all whom t mcysconccrn:

Be it known lthat I, HENRY NORMAND, a citizen of the `United States, residing at Waterbury, county of New Haven, and State of Connecticut, have invented an Improve.` ment in Snap-Fasteners, of whichthe fol-l lowing description, in connection with the accompanying drawings, is `a specification, like characters on the drawings.representing like parte. i. i

kThe invention to be hereinafter described relatesto snap fasteners for glovesandother purposes.V i i l These snap fasteners usually comprise a socket part and a stud `part securedfto fabrics tO be ydetachab'ly connected, the lstud 'of the stud part bei-ngv adapted tofsnap into .the socket `of the socket `part. to connect `the fabrics. A' "4 Y u One of the Objects Oftheinvention is to provide `a socket part comprising simple members which may be diedfout and formed from sheet metal, the construction of the members` being such that aftery placing the members on opposite sides of afabric, a neck of `one may be inserted into an .annular grooveinthe other, the `groove being formed to clench theneck to the .groove as the mem- 'bersare pressed together,tl1ereby effectively to secure `the membersto the fabric between them.

Anotherobject is to provide a stud part comprising simple `members which may be died out and formed fromy sheet metal, the construction of the :members being such that after `placing the members at opposite sides of a fabric, ,a neck of one `may be inserted into a recess of the iother, the recess being formed to'clench the neck to an Lin-turned flange surrounding said recessas the members are pressed together, thereby effectively to secure the members 'to the fabric between them. i.xl i

And lanotheryobjectlof the invention is to rprovide a socket part anda stud part, `each with a member having a `neck which. may force a portion oflthe fabric to which itis applied into the annular groove or recess of another member .so `as to effectively grip the fabric and contribute tothe securegassembly ofrthe members. i

Vith the aforesaid Land other objects "in view, the character of the invention may be Vbest understood. by reference lto the follow-` ing description of one goed formthereof Specification of Letters Patent.

Fig, Sis a plan of the socket memberand 'i its spring;

Fig. 4 is a bottom view of the socket member; and i Fig. i is a vertical section `through the parts shown in Figs. l and 2 showing `the members assembled and the parts secured to Referring to the drawing, the snap fastener shown therein as one good form of the invention comprises a socket part, in the present instance, comprising a cap ymember 1- ('F ig. l) having an inturned flange 3. This cap member may be4 of any suitable instal, and maybe smooth, decorated or marked as desiredrto constitute `the visible button of the fastener when the parts there of are snapped together'. This cap member is adapted to Vbe placed on one side of a fabric, v

the latter `term being selected herein as generic to any material to which the fastener is to be applied. i i

The socket member 5 (Fig. l)` has a hollow head 7 `formed therein preferably centrally thereof, and projecting a substantial distanceV upfrom the base 9` of the socket member. The circumferential marginof the base maybe pressed upward `and inward to present an iii-turned lip `11.

Suitable spring means Ina'y be mounted in the. socket member and coperatewith the hollow head thereoffto detachably connect .the stud of the studpart, `to be described, to the socket part. In the present instance, this spring means comprises` a wire spring 13 formed to present legs 15 projecting into diametrically opposed slots 17 in the socket head, reverse bends 19., and a curved portion 21 connecting said reverse bends. This curved portion may be located betweenv the base and lip of the socket member, as will be noted in Fig. l. 1.

The .socket member is adapted to be placed on the oppositeside of the fabnicfrom vthe cap member. An`important feature ofthe inventionrelates to means for connecting the cap 4member and the socket member.` .v To

accomplish this, in the present instance, an eyelet 23 is provided preferably permanently connected to the socket member. ,The lower end of theeyelet may'have an out-turned lip 24 which may be confined between the curved connecting portionof the spring andthe in?,

turned lip of thesocket member. |The` eyelet Vmay have a neck 25 adapted tobe connected with the capinember. To accomplish this, in the present Vform ofthe invention,

thecapmember l may be Vprovided with a l ring or member 27 v'containing an annular' groove 29 flaring upwardly so as to have a greater diameter at the base of the groove than at the open end of the groove which seats against the fabric. The ring may be Vsecurely retained in the cap member by the ineturned flange 3 of the latter.

' The Vconstruction is such that when the cap memberand socket member are pressed ltogether at Vopposite sides -of the fabric, the

end of the neck of the eyelet will be forced outwardly by the liaring groove of the ring, and thereby securely clench the eyelet to the ring and cap. The end of the neck of the eyelet may penetrate the fabric, or it mayI Vforce a portionof the fabric into the annular groove of said ring. ln the latter case the fabric may wrap around the end of the neck of the eyelet and be clamped to the ring when said neck is clenched thereto as described. The end portion of the necky may have notches 25a cut therein to facilitate the clenching thereof to 'the ring. y

The stud part of the fasteneiginthe present instance of the invention, comprises a is provided withy a base 35 formed to present a recess 37 between a circumferential shoulder 39 at the root of the stud, and an iii-turned flange 4l surrounding vthe recess. Preferablythe latter is formed to present a slightl curvature between` said shoulder and flange. The base of' the stud is adapted to be placed on one side of al fabric. Cooperating with this base is an eyelet e3 having a flange l5 for engagementwith the oppositey face of the fabric from said base, said eyelet having a neck/i7 adapted to enter the recess in said base when the eyelet and base are pressed together. ,The construction is such that the end of the neck of the eyelet will engage the recess of the base and be curved over around the curved surface of said recess and be clenched to the in-turnedflange engaging surrounding said recess. The: neck of the eyelet may penetrate the fabric, or a portion of the latter may be forced by saidv -neck into said recess, and in Athe latter; case the fabricwill wrap around theend ofthe neck ,andV be'iconfined between theV same Vand the in-turned flange of the recess. To facili-V tate the clenching of the neck, the end portion .thereof may have notches 47a cut therein. v Y A socket art and a stud part constructed asdescribed), may be securely attached to the fabrics to be Aconnected,.and will effec'- tively preventsaid parts from being pulled from the fabricto vwhich they are Vattached in vvpulling the stud member from the socket member to separate the parts' of the fastener. All'of the members of thefastener, Vwith the exception of the spring,pmay be conveniently died out of andformed from sheet metal, and said-members may be-'easily and readilyassembled. .Thus, there is provided a fastener which is very cheap in construction, but is strong and efficient in operation. It will be understood that the invention is not limited to the specific embodiment shown, but that-various deviations, 4may be made therefrom without departing from the spirit and scope of the appended claims :-V-' .What'is claimed 1s: r f .L
